vacuum CLEANING AP-PARATUS.

' Patented Jan. 1912. 620,113. Divided and this application filed Octo r 18, 1911. Serial No. 655,400.

Be it known that I, Louis l/Vi FLYNT, a subject of the King of Great Britain and resident of Rochester, in the county of Monroe and State of, New York, have invented certain new and-useful Improvements in Vacuum Cleaning Apparatus, of which the following is a specification.

This invention relates to vacuum cleaning apparatus, and has for its object a dustseparatoi in which the heavier dust is separated from he lighter dust and collected in a receptacle that is readily removable; also means whereby the finer particles of dirt "within acasing 22.

that enter the apparatus are subjected to steam .and heated. gases for the purpose of destroying them or rendering them harmless, before being discharged therefrom; and other improvements that will be described.

In the drawings :Figure 1 is a side view,

partly in section, of a vacuum cleaning apparatus embodying the invention in question; and Fig. 2 is a section on the line 2-2 of Fig. 1.

The invention is shown in the drawings in connection with a steam-generator and a steam-nozzle which, in conjunction with a draftpipe, constitute vacuum producing means in the form of an air-ejector. In the illustrated embodiment of the invention the generator is a flash-boiler 1 that is inclosed The lower end of the boiler is connected with a steam-nozzle 3 by a pipe 4 and a casting 5. The casting 5 with the steam-nozzle'3 attached is held in place by a nut 6 which draws the casting 5 tightly up against the separating chamher or compartment 7 and a bolt 8 that locks together the casting 5 and pipe 4. Thus the steam-nozzle is readily removed.

The draft-pipe 9 through which the steam-nozzle discharges is attached to a removable plate 10 that gives convenient access to the separating chamber 7. A pipe 11 surrounds the draft-pipe 9 and serves as a flue to conduct to the incinerating chainber'or compartment 12 the steam discharged from-the nozzle 3, and air and dirt withdrawn from the separating chamber 7-. Whenthe p pe 11 is pushed up into the mmneratmg c removed. The pipe 11'is held in elevated position by a hook 13 which turns inunder it, and the, plate 10- is held in place by two amber 12 the plate 10 can be' opens into the pipe or flue 11, as shown in Fig. 1, so that the air and the finer solid material are withdrawn by the air-ejector from the separating chamber and discharged \\1th the steam up through the draft-pipe thence into said'pipe 11, and thence. into the combustion chamber 12, wh ce they pass ofi through the pipe or fiuef 19 into the chimney of a building, or' to atmosphere direct.

The lower part of the separating chamber consists of a removable can 20 that is forced up into close contact with the lower edge of the upper part 18 of "the separating eminbcr by a spring-controlled bolt- 21. This bolt is represented as provided with a roller 22 at its upper end to serve as a bearing for the can 20, and is held lvieldingly up against the can by a spring 23,1ocated in a recess 91 in'the casting 25 on which the machine is supported by legs 26.' The bolt 21 is depressed, for the purpose of facilitating the placing and removal of the can, by a lever 27 which is connectcd 'with the bolt and is fulcrumed on the projection 28 from the casting25. The lever projects out throughan opening 29in thefcasling so that it can be operated by the foot, and stops 31 and 32 serve to center the can.

A burner 30 for heating the boiler is supported beneath the' boiler-coils. The hot gases and products of combustion rise from the burner and pass up through the incinerating chamber 12into the pipe or flue 19.

In operation the heavier material, such as sand, is'deposited in the removable can 1:"), while the finer particles, such as dust and germs, are withdrawn from the separating chamber 18 by the action of the air-ejector and discharged up through the flue 11 with the s eam into the hot gases and products of comb stion the incinerating chamber 12.

This application is a division of my 00- ment is supported, a removable vessel adapt-- -a dust-separating compartment open at the bottom, a base upon which said com artment is supported, a removable vessel a apt- .ed to close the bottom of said compartment, aspring-controlled device on said base for holding said vessel yieldingly in contact. with said compartment, and a lever adaptedto withdraw said device from said vessel.

2. In a dust-separator, the combination of a dust-separating compartment open atthe bottom, a base upon which said comparted to close the bottom of said compartment, and a spring-controlled device on said base, provided with a roller for engaging said vessel, and adapted to hold said vessel yieldingly in contact with the compartment.

3. In an apparatus comprising a steamgenerator and dust-separator, the combination of a steam-nozzle having a connection with the generator and discharging from the separator, a removable lid above the nozzle giving access to the nozzle end and to the interior of the separator, and a draftpipe intowhich the nozzle discharges and iyllch is supported above the nozzle by said t. In an apparatus comprising a steamgenerator and dust-separator, the pombination of a'steam-nozzle having a connection with the generator and discharging from the separator, a removable lid above the nozzle giving access to the nozzle end and to the interior of the separator, a draft-pipe into which the nozzle discharges and which -is supported above the nozzle by said lid. and a removable pipe adapted to rest iipon the lid, surrounding the draft-pipe, and

adapted to receive and conduct away the discharge therefrom. v

- 5. In combination, 'a dust-separating and incinerating receptacle comprlsing a, sepa: rating compartment having an inlet, an mcinerating compartment having an outlet, and a generator compartment provided with a boiler and with a burner .forheating the boiler, the generator compartment being arranged to discharge into the mcmeratmg compartment; a flue exterior to said receptacle leading from the separating compartment into the incinerating compartment (at a point above the boiler and burner; and

steam-driven means for inducing dustladen air into said separating compartment and for conveying particles of dust from said separating compartment through said passage'and thence into said incinerating compartment.

6. In combination, a dust-separating and incinerating receptacle comprising a separating compartment having an inlet, an incinerating compartment having an ontlet,=

and a generator compartment provided with a boiler and with a burner for heat ng tne boiler, the generator compartment being arranged to discharge into the incinerating compartment; a flue exterior to said receptacle leading from the separating co'mpartment into the incinerating compartment at a point above thelboiler and burner; and a steam-driven a1r-egector arranged to (11S char 'e through said passage and thereby with raw particles of dust from said separating compartment and discharge them into said incinerating compartment.

7. In combination, a dust-separating and incinerating receptacle comprising. a separating compartment having an inlet, an incinerating compartment having an outlet, and a generator compartment provided with a .boiler and with a burner for heating the boiler, the generator compartment being arranged to discharge into the incinerating compartment; 3. flue exterior to said receptacle leading from the separating compartment into the incinerating compartmentat a point above the boiler and burner; and a steam-driven air-ejector comprising a steamnozzle and a draft-pipe arranged to discharge through said passage and thereby withdraw particles of dust from said separating compartment and discharge them into said incinerating compartment.
